Abstract (en)
The present application provides a method and an apparatus for anti-repackaging. The method includes: running a target file in an installation package and loading a secure dynamic library in the installation package; and performing the following steps based on code in the target file: obtaining digital watermark information embedded in the target file and verification information stored in the secure dynamic library; and verifying, based on the digital watermark information and the verification information, whether the installation package is a repackaged installation package. Because the installation package in the present application includes verification code, no matter how an operating system is modified, a process of verifying the installation package in the system cannot be avoided. This alleviates an existing problem that whether the installation package is repackaged cannot be effectively verified sometimes when the system verifies a self-signature of the installation package to verify whether the installation package is repackaged. The following existing problem is also alleviated: verification efficiency is low sometimes when the system calculates a hash value of the installation package to verify whether the installation package is repackaged.
